This book for high school students lays out Euclidean geometry starting from analytic geometry.
Traditionally Euclidean geometry is one's first introduction to axiomatic systems and formal proofs. It seems to me that this book doesn't really make its axiomatic foundations very clear. Presumably they consist of some set of logical principles, plus some set of axioms for the real number system. These are all probably fairly standard, but they're completely off stage. Lots of statements are given without proof, e.g., that a unique line passes through any given pair of points.
There are no figures. This is a big problem for a geometry textbook.
